Title: Improvements in or relating to regenerative heat exchangers
IPC: F28D19/04
Filed: 1951-05-11
Abstract: 739,904. Regenerative heat-exchangers. CENTRAX POWER UNITS, Ltd., and BARR, R. H. H. May 6, 1952 [May 11, 1951 ; Sept. 14, 1951], Nos. 11182/51 and 21658/51. Class 64 (1). Relates to regenerative heat-exchangers in which the heat-exchanging fluids are passed in separated streams through a matrix by means of ducting which has a relative rotational movement with respect to the matrix so that individual portions of the matrix are alternately traversed by each fluid and in which seals are provided between the relatively moving members. According to the invention the seals are separated from the matrix face by passages A, B for the respective fiuids the cross-sectional area of these passages being smaller in the region of the seals than in the region of the matrix face. By this means, the fluid velocity in the region of the seals is relatively high so that fluid leakage at the seals is minimized. Either clearance seals or rubbing seals may be used. The invention is said to be applicable to apparatus in which either the matrix, the ducting, or both ducting and matrix are rotatable and particularly to apparatus in which heat is exchanged between air at high pressure and turbine exhaust gas at relatively low pressure. Fig. 1 shows a rotor comprising a matrix portion 1 and inner and outer hollow members 2, 3 which form the passages A, B separating the matrix faces from the ends of stationary ducting 18, 21 and 22, 25 conducting the heat-exchanging fluids to and from the matrix. On the high-pressure air side of the regenerator the seal comprises a spring-loaded sector-shaped plate 28 apertured to accommodate the ends of ducting 18, 21 the plate 28 being maintained at a running clearance from the rotor end face. On the low-pressure gas side, the sealing is merely by way of a small running clearance between the ends of ducts 22, 25 and the rotor end face. The rotor rotates on three angularly spaced rollers 11. The matrix 1 is divided into sector-shaped compartments containing cartridges of heat-transfer material which are removable for cleaning by withdrawing an end cover 9 of a casing 10 surrounding the rotor. Guide vanes 8 are provided in the passages A; B. An arrangement incorporating a disc type rotor is described.

Abstract: 737,661. Pit props. GERLACH, H. May 2, 1952 [Dec. 22, 1951], No. 11196/52. Class 20 (2). In a telescopic pit prop, the upper prop part, which may be tapered, is clamped in the-prop lock by means of two tightening devices acting between one of the prop parts or a part carried thereby and a rockable bearing means supported by the other prop part, the rockable bearing means serving to balance between the tightening devices the clamping thrusts exerted by the devices. As shown in Figs. 1, 2, the tightening devices comprise cross wedges 4, 5 engaging grooves 8 in a pressure piece 7 which bears against the upper prop part 1, the wedges also bearing against a rockable bearing 6 having an arcuate surface engaging a corresponding curved surface in the prop lock 3. At the opposite side, the upper prop part 1 bears against the lock 3 through a transversely rockable bearing 9 having a curved face 10 engaging a similar face of the lock 3. In a modification, the bearing 6, Fig. 3 (not shown), is interposed between the cross wedges and the pressure piece 7, the bearing 6 being rockable in the pressure piece 7 and the cross wedges engaging grooves in the lock. In a further modification, the wedges 4, 5, Fig. 7, are arranged at the ends of the arc defined by the bearing 6 and have similarly curved surfaces applied against the prop lock 3. In another modification, the wedges 4, 5, Fig. 5, are coupled to the bearing 6, which is rockably mounted in the pressure piece 7, through two movable clips 11, 12, the prop lock 3 against which the wedges bear merely comprising in this case a backing plate. In further modifications, the cross wedges may be replaced by eccentrics or one eccentric and one cross wedge used, or the wedges may be replaced by hydraulically-operated tightening devices. The balancing of the forces between the tightening devices may be effected through a bearing which rocks about a central curved counter-surface. The upper prop part may be provided with a drag wedge or the bearing 6 and pressure piece 7, Fig. 5, may be modified to be dragged down with the upper prop part on sinking in the lower part. The various bearing surfaces may be spherical instead of arcuate to provide universal adjustment thereof.

Title: Improvements in or relating to the manufacture of shaped articles of synthetic resin, especially refractor panels for lighting fittings
Inventor: FERGUSON HAROLD MATTHEW
IPC: B29C59/02
Filed: 1955-04-25
Abstract: The surface of a shaped article which has been formed by pressure moulding and consisting principally or wholly of polymerized methyl methacrylate is polished by bringing it into contact with a liquid or gaseous fluid, e.g. water, which does not dissolve or react chemically with the resin during the polishing step and which is at a temperature at or above the softening point of the resin, contact being maintained for a time which is sufficiently long to effect a polishing of the surface but so short that no part of the article becomes so heated as to lose its shape.  In an example a refractor panel made from polymethyl methacrylate is immersed in boiling water for 15 seconds and then plunged into cold water.

Title: Improvements in the removal of butadiene and acetylenes from aqueous cuprammonium
Inventor: MOONEYHAN WILLIAM RAY
IPC: C07C7/11
Filed: 1961-04-04
Abstract: Acetylenes and butadiene are separated from a solution of the gases in aqueous cuprammonium <PICT:0932503/III/1> acetate by heating the solution to a temperature of 100 DEG -120 DEG F. under a pressure of 180-195 p.s.i.g., passing the warm solution into a flash zone, maintained at a pressure between 45 and 55 p.s.i.g., wherein gaseous butadiene is desorbed from the solution, and then subjecting the solution to multi-stage flashing at increased temperatures and reduced pressures in order to strip out the acetylenes with minimum formation of polymers.  A crude C4-hydrocarbon stream is contacted in chiller 3 with aqueous cuprous ammonium acetate (CAA) solution.  The combined stream is passed to settler 7, and crude butadiene is taken off overhead. The CAA solution is pumped at a pressure of 180-195 p.s.i.g. into heater 12, where it is heated to 110 DEG F.  The warm solution is then passed into drum 14, maintained at 50 p.s.i.g., where butadiene flashes off.  This butadiene is freed from ammonia in water-scrubber 16.  The CAA solution, withdrawn from drum 14, is heated to 185 DEG F. in heater 21, after make-up ammonia has been added through line 20a.  The solution is passed into stripper 23 where the acetylenes are desorbed at a pressure of 30 p.s.i.g. This is followed by further desorbtion in stripper 30, which is maintained under the same temperature and pressure conditions as stripper 23. Finally the solution is heated to 200 DEG F. in heater 33 and flashed at 5 p.s.i.g. in stripper 35.  Make-up ammonia is injected through lines 27a and 32a.  The acetylenes desorbed in strippers 23, 30 and 35 are withdrawn via water scrubber 37.  The regenerated CAA solution is pumped through cooler 44 and char-remover 46, and is now ready to be recycled via line 2 to the crude C4-hydrocarbon stream.

Title: Improvements in or relating to the manufacture of artificial silk
IPC: D01D7/02
Filed: 1931-04-23
Abstract: In the production of artificial silk from regenerated cellulose by the wet spinning process, the spun thread is introduced at a speed of more than 60 metres per minute into a centrifuge revolving at normal speed, i.e. from 5000 to 8000 revolutions per minute, and the cake after washing or other treatment is brought with twisting directly into marketable form such as a bottle-bobbin, cross-wound bobbin, cop, or pirn.  In this manner, the twisting, produced in spinning into the centrifuge, which is insufficient for many purposes, is supplemented by a second twisting.  The cake may be subjected to liquid treatments either in the centrifuge or after removal therefrom and it may be wrapped in porous fabric or other permeable covering for protection.  For the subsequent twisting, the cake may be replaced in the spinning can which is rotated at normal speed while the silk is drawn off.  In order to obtain a variably twisted product, the spinning speed or the speed of unwinding may be caused to vary.
